Anyone know if this has a blocking diode built in? I have several panels wired in parallel and need to know, but the company has been slow to answer..... (Update) I'm not worried about frying anything, just efficiency. If multiple panels are wired in...

I am reasonably certain that there is no blocking diode on the panel. I bought two panels and put in my own diodes.

I THINK so, Friend Sutherland... This unit SEEMS to have no built-in Loading Resistor Array (as my other one had) to overheat and raise the Stench Level. This unit clearly tests for UNLOADED PSU voltages; imho the price reflects that lightweight design. OTOH, searching the Web on the terms [ ATX Molex pinout ] will reliably reveal the Two Magic Pins that are momentarily connected to each other in order to to start the works whenever the Box's front-panel button is pressed from cold-start... One wee jumper, permanently bridging those two adjacent Molex pins, will Just Do the Job for No Money. That's what I do in MY lab whenever called-for. Hasn't ever failed me. Just doing what the test appliance does, is all! ;) And that is all. 0{;-)o[

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

I'm reading a lot about needing to be on the same circuit breaker. Is this really a problem with being on the same power legs at the breaker panel. In this case the problem would be resolved by making sure the same power leg is used at both ends. Need to know before I buy as I would be passing thru different breakers but can put them on the same power leg.

I just reviewed the pictures you have online for your solar panel setup. I have the following suggestions. Its hard to tell how the meter is wired but you may want to check the wiring with the online diagram. I'd recommend moving your battery setup to a less flammable location. The way you are charging all your 12V parallel batteries does not allow for balanced charging so any one of your parallel sets could get out of balance, be overcharged and explode. Look up "thermal runaway". You should probably have some type of temperature monitor on you system or just may sure your batteries stay cool when charging/discharging. Good luck.

Just an update to my earlier post. Each fuse has it's own circuit/power source. On my 5'er I just unplugged the existing wires and attached them to the terminals on the new panel.

Well, I guess the question was - IF a surge appears on line and burns up the protective circuitry, will this item still continue to provide power to equipment connector to it? The problem with it doing so is that the equipment hooked to it now unprotected. I'm looking for an answer myself, so more info from owners is welcome..

It's rated at 20amp. Each of these panels are rated at 5.7amps. It should handle 2 panels, perhaps 3. I would think 4 panels would begin to limit the amperage. You can also use multiple charge controllers rather than trying to attach a larger array of panels to a single controller.

Just a note these controllers wont do zip when the input amps are below 15. The two Panels most likely will not enough to fire is up. DM 145 Watt panel crank out on;y 7.7 each amps on a good day. I Bought this CC and had an electrician (Who Wasnt Cheep) confirm this about the CC. Dont get me wrone thee CC will work but you will need to put three 124 watt panels on it. If you want a CC controller that will do the two with ease. Check out the HF CC 30 amp 500 watt CC by thunderbolt. Its about the same amout of cash on amazon. Good luck on your decision.PS If you go with this one the manual stinks. Learn chinese Just a note these controllers wont do zip when the input amps are below 15.

Hmm That does sound like a serious issue! I cannot say that I have had that problem yet and I have 8 units installed in my house. It sounds to me like the unit is placed on a circuit that is beyond the recommended load which can easily happen. In other words, this issue sounds like people are using the units on circuits that were already poorly wired. Just my thoughts.

It is not recommended through a surge protector. It may not work at all or will be unreliable. I do not know if has one built in, but I have three and have been using them for over a year with no issue.

It may overcharge your battery though not likely.It does have a bypass diode which is only useful when connecting multiple panel in series. The diode has nothing to do with overcharge protection.You should consider adding a diode in series with the + lead to prevent leakage at night. Again this will have no effect on overcharge.It may be easier to add a charge controller.

I am not sure if it would block everything. A Lead liner is the only thing that would do it for sure and I don't know how it would be done safely. Should you try the conductive shielding (ArgenMesh), I would double the layers&gt; This is just my thoughts, I could be wrong!

Check with your electrical inspector. That being said I used 2 of the available spaces and mounted a 100 amp main. Still have 2 extra spaces and doubt I'll ever come close to using more than 100 amp. No main was required by local codes but I like to be able to kill all power to box. Hope this helped.

My understanding is that 4 panels can be linked together but no more without having a separate controller. Call the company, their customer support is amazing.

The seller's answer should be taken as definitive. Anecdotally, my installation is not on a dedicated circuit, but the other members of the circuit are either outlets or efficient lighting. I've had my unit in service for over 6 months with no issues to speak of. Enjoy!

Does this unit have hardwire ac output? If it does not, how would I wire this into an off grid ac electrical panel to supply circuits for electrical outlets and lights for a small cabin. Note there is no electrical company power lines coming into the panel). Thanks!
